PLASTERING AND ORNAIVIENTING WALLS AND CEILINGS.

SPECIFICATION forming part of Letters Patent No. 245,237, dated .August 2, 1881.

Application filed May 2S, 1881. (No model.)

To all w/L'om fit may concern Beit known that we,'DnvrD W. S'rooKsfrrLL and THOMAS J. MGGEARY, both of Washington, in the county of Washington and District 5 of Columbia, have invented a new and valuable Improvement in Plastering and Ornamenting falls and Ceilings; and'we do hereby declare that thel following is a full, clear, and exact description of the construction and operation of 1o the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and iigurcs of reference marked thereon.

Figure l is a plan view of a mold forming a center-piece. Fig. 2 is a sectional view of the same. Figs. 3, 4, 5, and 8 are cornice-molds; and Figs. l5 and 7 are sections ofthe same.

This invention has relation to improvements inthe art ot' plastering, whereby centers, cornices, and ornaments ot' any character can be produced by the direct application of the newlymixed or soft plaster or composition to the wall under a molding pressure.

Heretofore'it'lia'sbeen customary for plasterers to purchase previously-molded centers,

cornices, and or-namentcd work used in decorating the interiors of apartments and buildings; and right-line cornices and moldings have been formed on the wall with newly-mixed plaster by means of a former or profile scraper, which is drawn along the outer portion ofthe mass of plaster. A mold has been secured beneath a ceiling, and liquid composition run in from above the ceiling, and the liquid composition then permitted to dry and adhere to the ceiling before the withdrawal or removal ofthe mold. This method of forming ornamented walls or ceilings, however, differs from the method or process herein described and claimed.

The present invention has no relation to such devices, but is designed to enable the plasterer, with the same newly-mixed stock which he uses in surfaceiinishing the wall, to put up 4 5. centers, cornices, or ornamental devices of any igure or pattern which will readily draw from a mold. -The process is so simple that, if desired, an entire wall can be ornamented in low relief or inta-glio by any plasterer of ordinary skill in his trade.

The invention consists, tirst, in the art or process of forming centers, cornices, or other ornamental surfaces in place by molding the plaster immediately on the Wall 5 and, secondly, in M oidjpga mold adapted`to receive the plaster', to apply'tlems-alctfcjlthe wall, and to draileasily therefrom, substantially as hereinaitcr set forth.

ln the accompanying drawings we have designed to illustrate several forms ot' molds which may be used in carrying out this invention. These forms may be varied in many ways, the object being to provide a mold which islight enough to be readily handled, and which has sufficient stiffness or body to support the material placed upon it and to withstand the pressure used in applying the same to the wall. In practice it is preferred to form these molds by pressure from sheet-zinc, or some composition in whichzinc is an element, althougha different material may be used, if thought desirable.

The molds arepressed bymreans of dies, usually, and may have the Vcontiguration in relief or intaglio and according to any design. The letter A indicates a mold for a central ornament, and B a mold for a cornice. These molds should beprovided withangcs a, which are designed to serve as a guide to the workman, enabling him to apply the plaster with precision and facility. Handles b may also be attached, and will render themolds much more convenient. A miter-mold can be made by forming at one end of the main mold a projecting liange of the same pattern as indicated in the drawings at c.

For continuous work, such as cornices, moldings, and friezes, the molds employed are made sufficiently long to be conveniently raised and handled by the plasterer, about thirty inches being the usuallength. These molds are usually provided with shouldered or abutting flanges d, so that a neat joint in the plasten IOC receive the plaster, which is put therein, in its newly-mixed state, in sufficient quantity to project a little, so that when the mold is pressed in place against the wall the plaster will adhere thereto. After the plaster has setv the mold can be Withdrawn foruseagain. In preparing the mnanisaivisabe..maaar.wen its interior surfacepbefore puttingin the plaster, the drawing of the in oldbeing facilitated thereby. As the metal which is usually employed for these molds is not rigid, but possesses a certain/amount ofelasticity, it can readily be sprung awayhfroin'the Work.

This invention is designed to enable those who build houses to greatly enrich the interior and exterior of the same at small expense. It will assist the plasterer in his journey-work, rendering it of more value, and will save the costotl transporting plaster-castin gs from place to place. Houses in country localities can be ornamented as cheaply as those in cities and towns. A saving of material is also designed to be accomplished by this invention, because in practice the plasterer will only use suffr cient stock to form the ornamental surface and the attachment edge therefor.

Having described this invention, what we claim, and desire to secure by Letters Patent, 1s-

l. The process of pressure-moldingplaster or composition described, consisting in first fllin g a portable mold with soft plaster or composition of proper consistency to hold its form so that it shall project a little from the mold second, moving the filled mold against the wall or surface, so that the plaster or composition shall adhere by itsprojected portion; and, nally, removing'the mold, leaving the ornamentation in place, substantially as specified.

2. A pressed sheet metal mold provided with guide-flan ges, and adapted to receive the plaster or composition, to apply the same to the Wall, and to draw easily therefrom, substantially as specified.

3. A plasterers mold for ornamental work, pressed in form from sheet-zinc or zinc composition, substantially as specified.

In testimony that We claim the above We have hereunto subscribed our names in the presence of two Witnesses.
